However, in damaged hearts, many of these cells cannot multiply or produce new muscle tissue. In these cases, it could be possible to replace the damaged cardiac stem cells or add new ones by growing them in the laboratory and administering them intravenously.” 
The research is published in the latest edition of the journal Cell.
